[asan] A clang flag to enable ELF globals-gc.
This feature is subtly broken when the linker is gold 2.26 or
earlier. See the following bug for details:
https://sourceware.org/bugzilla/show_bug.cgi?id=19002
Since the decision needs to be made at compilation time, we can not
test the linker version. The flag is off by default on ELF targets,
and on otherwise.
